Hello!
I am talking about inground swimming pool. We have a "vacuum cleaner" (I'm not sure how exactly to call it) - the water pump that goes under the water that is connected with a tube in a hole in the swimming pool to clean up dirt of the bottom. There used to be enough pressure for pump to do the job. But since couple of months it doesn't do the job properly even after we changed the pump completely. Then we were told that there can be holes in pipes under the concrete of swimming pool where the water circulates. Can it be true?
If it is true, I guess it is very expensive to repair, right?
How to check it out by yourself? (as it is very expensive to invite professional just for a visit to have a look $150-$250)
No water pump pressure, what is broken?

Usually if there are holes then the pool will lose water. Leaky suction line pipes also allow the pump to suck air and, depending on the rainfall/ water table, it can suck mud or sludge too. Have you noticed any of these symptoms?
You could try using a garden hose from the pump side to try blow water backwards into the pool as there may be a blockage on the vacuum line. Mains water pressure is high, so care must be taken not to damage the pipes with excessive pressure.

Dear Larry,
Thank you for the answer.
We've checked all that and still the same problem.
What's next?

What happens when you close the skimmer and main drain valves?
Does the vacuum line pressure increase?
Does the filter pressure gauge drop? If so, how much?
Does the pump suck air and lose prime?
Is there a vacuum port (hole) in the skimmer under the leaf trap? Try plugging the vacuum hose in there.

the pressure goes down, pressure become very low and engine working very hard.
the pressure of vacuum cleaner decreases, very low, it goes all right at first but then low low low, doesn't suck. but vacuum cleaner was checked its all right, something is wrong in the system.
the filter pressure gauge drop very much - I don't know how much, but very low, nearly zero, the lowest level.Does the pump suck air and lose prime? - No
Is there a vacuum port (hole) in the skimmer under the leaf trap? - tried, a technician came over and no problem with it.
we have only one problem, pressure go down
